Some of the stuff makes it easier
The Metro devs mentioned that with rayvtracing it saved them heaps of time and effort because they just turned it on did a little optimized and then it just works. Without it they would have to spend heaps of time placing lights around the maps and testing and making sure the lighting model works

Wouldn't that mean they have to do two lots of lighting? Unless they made the game for ray tracing capable cards only lol.

tried playing it again tonight. fk, it's so buggy. I'm always getting a good 1-2 seconds behind cover only to have died on the other players screen first. I'm pretty sure they made the TTK a little longer than it was originally like in the beta/release, even after their "roll back".

Nah that just means the lighting will probably look shitty if rayvtracing is turned off
It’s gimpworks all over again - no way of devs agree to do rayvtracing to save time do they then go and add all the usual traditional lighting in as well

This is my bet: in the new metro you turn rayvtracing on = better than Ultra lighting compared to other games
Turn rayvtracing off = Low settings compared to other games

* DLSS can only be turned on in this game if Ray Tracing is turned on first
* DLSS can only be turned on if MY base resolution is set to 4k - I put "MY" in upper case because while I was not able to get DLSS to work at 1440p, others have managed to force it to run even down to 1080p using console commands
* There is a image quality downgrade***

*** The change in image quality is less noticeable the higher your resolution is - so i.e if you force DLSS on at 1080p it look like it's running at 720p - running DLSS at 4k looks like around 1600 or 1700p so it's still decent.
Additionally I could not really notice the image quality difference sitting on my couch - I think this is due to the 1 meter sitting distance, it's obviously far easier to notice that if you are playing at your desk on a monitor
